I thought I needed a new battery in my garage door opener,so I purchased 2,because that's how they came,10.50 for 2.big waste of time and money!door still would t open and it was making a funny noise. I ended up calling my land lord which I dreaded,and he thought he fixed it but as soon as he left door would not open.so he is replacing the motor but not u til Monday or tues.my car has never sat outside before so I hope it starts.
